Ziming Zhang and VictorV discovered that the QEMU SLiRP networking
implementation incorrectly handled replying to certain ICMP echo requests.
An attacker inside a guest could possibly use this issue to leak host
memory to obtain sensitive information. This issue only affected Ubuntu
18.04 LTS. (CVE-2020-10756)
Eric Blake and Xueqiang Wei discovered that the QEMU NDB implementation
incorrectly handled certain requests. A remote attacker could possibly use
this issue to cause QEMU to crash, resulting in a denial of service. This
issue only affected Ubuntu 20.04 LTS. (CVE-2020-10761)
Ziming Zhang discovered that the QEMU SM501 graphics driver incorrectly
handled certain operations. An attacker inside a guest could use this issue
to cause QEMU to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2020-12829)
It was discovered that the QEMU SD memory card implementation incorrectly
handled certain memory operations. An attacker inside a guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service. (CVE-2020-13253)
Ren Ding and Hanqing Zhao discovered that the QEMU ES1370 audio driver
incorrectly handled certain invalid frame counts. An attacker inside a
guest could possibly use this issue to cause QEMU to crash, resulting in a
denial of service. (CVE-2020-13361)
Ren Ding and Hanqing Zhao discovered that the QEMU MegaRAID SAS SCSI driver
incorrectly handled certain memory operations. An attacker inside a guest
could possibly use this issue to cause QEMU to crash, resulting in a denial
of service. (CVE-2020-13362)
Alexander Bulekov discovered that QEMU MegaRAID SAS SCSI driver incorrectly
handled certain memory space operations. An attacker inside a guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service. (CVE-2020-13659)
Ren Ding, Hanqing Zhao, Alexander Bulekov, and Anatoly Trosinenko
